Episode 177: Cambrian Fecal Revolution

Cambrian fossil evolution

The Cambrian Explosion is one of the most significant events in evolutionary history. Classically, it describes the sudden appearance of complex fossils (including all major animal groups) at the beginning of the Cambrian Period. Before then it was thought that only relatively simple single-celled or multicellular life existed. We now understand this event to be [&hellip

Remarkable Eoceras shaanxiense Fossils Rewrite Cephalopod Evolution

China Cambrian Stage 3 fossil evolution formation

Researchers have identified tiny fossils from the Shuijingtuo Formation (Cambrian Stage 3) of South China that could transform our understanding of cephalopod evolution. The newly described species, Eoceras shaanxiense, provides the oldest known evidence of a primordial siphuncle, a crucial anatomical feature that enabled cephalopods to regulate buoyancy and eventually become some of the oceans'

520-Million-Year-Old Fossil from China Fills Gap in Evolutionary History of Cephalopods

China Cambrian fossil evolution

Paleontologists have identified the earliest-known cephalopod equipped with a siphuncle -- a tubular extension of the mantle found in shelled cephalopods -- pushing back the fossil record of this key evolutionary feature to the Early Cambrian, roughly 520 million years ago.
